Operating Systems

I am facing a strange problem with my computer. From last week i am getting a sudeen kind of response from my computer. My computer satrts to freeze after approximately 5 hours of constant work. I noticed it it many times. I don't understand that what is letting the computer to freeze at normal working even i am not playing any games. Please provide soem views regarding this problem

Download and run SensorviewPro to see what your temps are. Try it when idle (just starting up) and when you put it under stress (playing a game). Also, check the voltages and post them from that program. This way, we will know what is happening in that rig.

We may have to look at thermal paste being redone. Also, tell us what cooling fans you have, where they are placed, and which direction they are blowing.

i think i have a similar problem on my desktop computer. after a few hours of being on, the hard drive will start going crazy but i will not be able to move the mouse or type. Do you think it is the same problem. what will happen if i run 'chkconfig cpuspeed off' in a terminal?
